Incline to take a different stance (6)
I believe the answer is:
ascent
'incline' is the definition.
(I know that ascent is a type of incline)
'a different stance' is the wordplay.
'a different' is an anagram indicator.
'stance' is an anagram of 'ASCENT'.
'to take' is the link.
(Other definitions for ascent that I've seen before include "Mountain path" , "Enacts in climb" , "Upward slope" , "lift" , "Stance (anag)" .)
